Everything your daily posting needs

One template, filled fresh every day — dates, ages, milestones and math, computed for you.

Smart templates

Write once with variables like {weekday}, {day} {month} {year}, {title} and {moment} — every generation is date-perfect.

Live age tracking

Family & baby pages: real-time ages per child — {child1_age}, day counts, months — computed to the second.

EXIF autofill

Attach a photo or video and the capture date, GPS and place name fill your caption automatically — parsed in your browser.

Custom placeholders

Save your own snippets — {shop_name}, {cta}, {channel_link} — and reuse them in any template.

Formulas & math

Calculations inside captions: {=({days}/7)} for weeks, percentages, totals — with round, floor, min/max and more.

SEO post pages

Every publish gets an Instagram-style page with a clean date-wise URL, Open Graph previews and an auto-updated sitemap.xml for Google.

How creators use it

The same engine, pointed at different feeds.

Instagram & Reels captions

Daily milestone pages, shop posts and family journals — consistent captions with hashtags, dates and ages, plus a link-in-bio-ready page for every post.

YouTube descriptions

Templated descriptions with your channel links, upload date, episode math like {=({days}/7)} weeks running, and consistent CTAs.

A public archive that ranks

Your posts live at date-wise URLs, grouped in a crawlable archive with a sitemap submitted to Google — so people find last month's moment, not just today's.

From template to post

This template…

{weekday}, {day} {month} {year}
?? {title}

{moment}

Week {=round({days}/7)} of {name}
?? {child1_name} • {child1_age}
?? {location}

{hashtags} {cta}
